How salsabila221/geosense-node works

GeoSense_Node is embedded geophone-monitoring firmware. Its main loop samples an ADS1220, updates STA/LTA event state, analyzes completed waveform windows, then conditionally logs and schedules radio telemetry while refreshing an OLED status display. Configuration and timing utilities support this workflow. The README is empty; edges are grounded in the shown main-loop calls and OLED implementation. Driver internals and several hardware connections are not shown, so those relationships are omitted rather than inferred.
